Life Size Animatronic Wolf Tail

We’re not 100% sure the usefulness of this hack, but it is extremely interesting regardless and will probably make a lot of furries happy. WolfTronix presents their method for creating a realistic animatronic wolf tail. It uses an Atmel MCU controlling two servos alongside a mess of Klixx toys and paper clips to produce a nice wag motion. The guide is extremely detailed and looks to be fun, so long as you don’t mind the monotonous task of shaving off potentially hundreds of ‘nubs’ as they call them. Either way, you’ll definitely have the best (and only…) tail on the block.

Humanoid Robot + Homebrew Waldo = Big Smiles

Robot enthusiast [Vitalijus Rodnovas] built this rig to allow a humanoid robot to mimic his own body movements in real time. [Rodonovas] refers to his man-machine interface as a “master-slave suit,” but elsewhere this is often called a waldo after a prescient 1942 [Robert Heinlein] novella. This project page is slight on details and is mostly written in his native Lithuanian, but the pictures speak volumes, and with a little help from Google Translate we can learn the essential facts: The robot itself is a commercially-available kit, the Kondo KHR-1HV from Japan. The custom-built harness uses a collection of surplus Soviet-era military potentiometers (acquired on eBay) to read the positions of his elbows and shoulders, then an ATmega8-based interface board translates these readings into motion commands sent to the robot’s onboard controller. Some additional notes and code can be found on the RoboSavvy Forum.

Does it work? Just watch. His grin as the video progresses is infectious!

Hack a Day has previously covered other Waldos, but this latest deserves style points for its lightweight simplicity.

Modular Computing

This is the Illuminato X Machina, a “cellular” style computing system. Each unit is a fully functioning computer with its own processor, storage and communications. You can watch above as a change in the operating software is propagated across the grid. You can see the LEDs in the video going nuts, there are actually LEDs on the sides too. [Justin] described it to us as a personal fireworks show on your desk. This system is fully open with the schematics and source code available on their site. You might recognize these guys too, we covered their Open Source GameBoy.

Hackit: Ideal Conference Badge?

August 11, 2009 by Eliot 28 Comments

In 2006, Defcon 14 premiered a unique electronic badge. All it did was blink, but it raised the bar for what was expected from a hacker conference badge. In 2007, they went from 2 LEDs to 95 in a scrolling marquee. Along with a POV mode, the badge had two capacitive switches to let the user edit the displayed text. Defcon 16’s badge featured an IR transmitter and receiver for transferring files from an SD card. It worked as a TV-B-Gone and had pads to access a USB bootloader. That was the same year that The Last Hope debuted their RFID tracking badges.

This year the official Defcon badge reacted to sound, but they were no longer the only game in town. Ninja Networks brought their 10 character party badges with a built in debugger. The Arduino compatible HackTheBadge 1.0 also made an appearance. With these new entrants into the field, we wondered what you’d want to see in your ideal badge. What badge would you want to see at next year’s Defcon? Leave you comments below and keep in mind that it should be an idea that is easy to cheaply mass produce.

UPDATED: Forgot to mention the Neighborcon 2 badge based on the GoodFET20.

HackTheBadge 1.0

August 10, 2009 by Caleb Kraft 17 Comments

[Martin] tipped us off to HackTheBadge 1.0. Possibly more elusive than the NinjaBadge, HackTheBadge has a Dpad, a 3×5 LED matrix, Arduino compatable headers, and 46 GPIO channels. You can download the open source plans if you didn’t get one at Defcon. You probably didn’t, there were only 14 given out. You can also order one pre assembled. This makes us wonder, does being low in quantity qualify this as elusive?

Vacuum Gloves For Climbing Buildings

Suction is incredibly powerful and can be put to use in several different ways. [Jem Stansfield] built a set of vacuum gloves for a BBC TV series to show how powerful suction really is. He climbed up the side of a 100 foot building, yet had to rely on his safety line near the top. The video of his daring ascension after the jump.

Volver is a 3.75 inch square LED matrix that will display over 1600 unique patterns. Designed by members of Image Node and Disorient, it is a fundraiser for burning man 2009. While it is certainly less colorful than its older sibling the Nodeblinky, it features 8 more LEDs and a bit smoother and faster graphics. Volver can be picked up as a kit, or fully assembled from their site. Just like last time, you don’t have to buy from them. They freely offer the source code and schematics.
